Improvement in planing-machines



UNITED STATES PATENT Ormea@ ALONZO T. BOON AND JOHN OOLLlS, OF GALESBURG, ILLINOS.

IMPROVEMENT IN PLANlNG-MACHiNES.

Specification forming part of Leiters Patent No. 43,001, dated June 7,1864.

To @ZZ whom it may concern.-

the county of Knox, in the State of Illinois,

Ilaning, Oornering, Boring, and Sawing; and We do hereby declare that the following is a full, clear, and exact description thereof, refan d to the letters of reference marked thereon. Figure lis a plan or top view of our machine; Fig. 2, a side view Fig. 3, an end view Fig.

combined.

Like letters indicate like parts in all figures of the drawings.

rlhe nature of our invention has reference to ing-bit, planing-knife, and circular saw on one end of the driving-shaft in the machine, wherescribed more particularly.

To enable any one skilled in the art to make and use our invention, we will proceed to del scribe its construction and operation.

We construct a frame, A, nearly square in appearance and of a suitable size, all of its parts being secured in a substantial manner.

and near the top of the frame, is a table, B

flush with the two inner uprights, b b, of the frame. The table by means of the braces is e. The screws pass through slots in the uprights, and are made fast to the braces. The

wooden material to be operated on is raised The vertical screws ff, as seen in Fig. 3 in dotted lines, are inserted inthe uprights from l the top ofthe frame, and pass down through the Iy cross-screws for the purpose of steadying the v supported by two braces, a a, as seen in Figs. 'j 2 and 3, each of which is directly opposite and table, the cross-screws embracing them in a sufficiently loose manner as to admit of their sliding easily up and down. The drivingshaft D is placed about the center and on top have invented a new and useful Machine for l of the frame. On the end over the table is l placed the circular saw G and planing-knife l H, both of which are screwed on and are made secure by nuts and washers, or by any wellerenee being had to the annexed drawings, l

known mechanical means. Screwed onto the l extreme end is the boringbit, as seen in Fig. 4. The result of this arrangement is, when the operator wishes to saw and plane a board, 4, a view of the driving-shaft, detached from the machine, showing the arrangement of the boring-bit, planing-knife, and circular saw i sawcd. rlhe planingknife, being on the left,

cleans oft' the rough surface while the operation of sawing is heilig performed` Either one of the three may be used alone by removan arrangement and combination of the boring the other two from the shaft; but before the operation of planing and sawing can be i done the adjustable jaws or gage-bars J J by the functions of boring, planing,'sawing, and cornering is done, the latter being per formed by means of adjustable jaws or gagei bars resting upon an adjustable table, both of 1 which are essential features in our improved l machine, and which will be hereinafter del ofthe frame, and are supported by standards g g resting on the table. lhesc standards are hinged on the side at or near the bottom by metallic loops 7L h, embracing the two standj ards, which are placed near the ends to allow f a free and easy movement to the jaws. The two outer standards are kept in their proper On one side, to the left and nearly the length places on the table by small pins or rods Z l, inserted under the bottom of each, and then into the table, or by any mode that will keep them in place and allow of their being conveniently removed when desired. Secured to g the inner standards, near the top of the jaw held and kept to any desired place on the side j of the frame by screws c, nuts d, and washers or gage, are ratchet-levers 'i i, which pass through slots in the outer ones, as seen in l Figs. 2 and 3, and serve to clamp or gage the inner jaw to the outer one at any angle that table to accommodate the board or other may be desired, thereby embracing the matey rial in such a manner in its passage over the and lowered according to the thickness ofi same in its relation to the feed rollers C C.

planing-knife as to enable the operator to control it for cornerin g or straightening the same. The ends of the outer jaw have braces jj' secured to them, as seen in Figs. l and and extend over to on the top of the frame, and

.then secured to the same by screws. The

outer jaw can be extended from the inner one by loosening the screws, the braces having slots near their ends on the frame to admit of its being` done. By removing the screws entirely, the jaws may be removed froln the table when desired.

The advantages of this machine will be found to be very useful and convenient to farmers and other persons Where the facilities for doing the kind of Work above described is not at hand, and where it is not desirable in a pecuniary respect'to have their work done at a large factory or shop. lts lightness and simplicity of construction and portability' enable them to obtain one at a trifling` cost, comparatively speaking; or, if it is found desirable, by purchasing -the proper material i pertaining,` to it, one may be readily constructed, and when steam-power is not convenient to drive, it horse or water power may be used, which makes it more advantageous to this class of persons than any other.

Having` described our invention, what We claim, and desire to secure by Letters Patent 1s- In a machine for planing, sawing, boring, and cornering, the combination of the adjust1 able side table with the adjustable jaws or gage-bars, as constructed and arranged, when used in combination with the planing-knife, saw, and boring-bit, as arranged on one end of the drivin g-shaft in the fra-nie, for the purposes above mentioned, and as herein described and set forth.
